Question to Faces ConfigurationEditor and Converters [message #473826]

Hello to everybody,

I "migrated" an existing JSF - project from an older wtp - Version to
the new one and "activated" the use of JSF-Tools by defining a new
project and transfering all project - files to the new project.

Now I can use the Faces Configuration Editor and it really looks very
promising - great work and thank you for this tool!!!

But I also have a Problem now:

The jsp - Editor now shows me an error in my jsf - files:
In all passages where I use the standard DateTimeConverter it says:
"EL expression does not evaluate to expected types for this attribute" -
it seems, that it doesn't recognize the standard-converter.

Here is an example-code-snippet that produces the error:

<h:inputText styleClass="fliesstext"
value="#{messMittel.rekalibrierung}"
<f:convertDateTime pattern="dd.MM.yyyy"/>
</h:inputText>

So I changed the code to:

<h:inputText styleClass="fliesstext"
value="#{messMittel.rekalibrierung}" converter="javax.faces.DateTime">
</h:inputText>

but I still have the error.

Then I tried to configure the Converter in the Visual Configuration
Editor and to set it as default converter for the managed-Bean
"messMittel", which is of type "PruefMittel":
(snippet from the resulting faces-config.xml):

<converter>
<display-name>
Datum</display-name>
<converter-for-class>
fachklassen.PruefMittel</converter-for-class>
<converter-class>
javax.faces.convert.DateTimeConverter</converter-class>
</converter>

But I still get the mistake.

I'm sure, I'm missing something, but I don't know what ...

Thanks for any help in advance,

Martin Zwosta

Hi Martin,

This is most likely our bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=149753

When a converter is nested like that, validation doesn't properly detect
it. Sorry for any inconvenience. If you are in doubt in these
situations, try running a test case on a JSF runtime and see if it works
as expected.

CC'ing yourself on the bug above and adding any additional comments will
help us prioritize a fix.

Thanks,

Cameron

No problem at all - it's the other way round: I'm thankfull for your
project and the jsf - editor etc.! I like it a lot!

Yes, that's what I did up to now, so I just continue doing that.

I just did that - will there be an email, when the bug is resolved?

Thank you very much,

Yes, in fact you will receive an e-mail from Bugzilla every time somebody
adds something to the bug, changes its state etc.

Thanks,
